Correct. It allows you to run different fuel at different power (boost) levels with timing changing accordingly

I'm still confused.... your saying that's correct it won't change boost levels, then yes it allows different boost levels..?


I read the entire thread and still no clear answer, will this automatically adjust boost levels with different mixes of fuel? Simply put; would you be able to run a pump gas boost/power level, add e85, and without flashing run higher boost/power levels? From what little I can decider to this, it looks like the answer is no. It will adjust the fueling requirements to maintain the current tune, but no boost nor power level adjustments.

I believe it can change load request which changes boost.

Where can we get the XDF for this?

If it doesn't change boost, and timing levels based on E content its worthless, so my guess would be yes it does this.

I hate cross posting from other forums, I feel that's "poor form", but I kind of have to:

jyamona said:
You do get to specify what your tune is targeting, through the set of interpolation % maps, for fuel, timing, and load. Each has 8 cells, so you can, for example, set your targets for E10, E30, E40, E50, E60, E70, E85, E98 if you wish. Or any other interval, that's the beauty

Question- assuming this will work in concert with any stand alone PI injection controller as well...?

There are a few ways to get it to work with a standalone PI controller I can think of. If the PI controller is unaware of ethanol content, the DME controlled DI could compensate the total fuel delivery by an exaggerated fuel scalar blender.

Yes, this works with standalone PI. @jyamona has said there is an additional output from the ECA that goes to your PI controller to allow it to run a custom flex fuel mapping as well (that he will provide).

Bump for an update.

Realistically at this point @jyamona is in a lose/lose situation here. He can not give an update and people will be pissed. He can give an update that things still aren't ready yet but here's the status and people will be pissed.

There's no reason for him to take a beating until the update is, "It's ready for purchase guys and here's your link".

Sucks but true.

So....being back in the N54 scene only recently, I’m not as well versed in the hot points for this crowd. I’m a quick study, but still getting up to speed.

I am also starting a build and I am simply researching/acquiring products for the build.

Aww man, now days you have to disclose what record you are going for before you do it to be legit bra.

I’m going for the Black DCT single turbo with three floor mats a factory glovebox 245 front tire trunk liner removed 1/2 mike standing start while smoking a Cuban cigar record.
